An Infant Is Shown an Object, Such as a Rod

An infant is shown an object, such as a rod, which is partially hidden by another object, such as a block. In order for us to conclude that an infant perceived the rod as two separate rods, how would an infant have to respond in a subsequent trial in which she/he had a choice between looking at a single continuous rod or two separate rods?

A) The infant would look longer at the single rod.
B) The infant would look longer at the two rods.
C) The infant would divide his or her attention between the single rod and the two rods.
D) It is not possible to determine whether infants without language think the rod that is partly hidden is a single rod or two separate rods.
